OF MOLINE, ILLINOIS, A CORPORATION OF ILLINOIS.

CULTI'VATOR.

Application filed. April 25, 1916.

To all whom it may concern:

Be it known that I, WILLIAM L. PnUL, a citizen of the United States, residing at Berkeley, in the county of Alameda and.

lar numerals indicate identical parts Figure 1 is a side elevation of part of a cultivator, with the wheels removed, illustrating the application of my invention.

Figs. 2 and 3 are detail views.

To a frame 1, I rigidly secure a draft pole 2; depending from the frame 1 is an arch 3 on the lower ends of which are journaled, and adapted for vertical movement, the forward ends of gang beams 4 carrying standards 5 to which are secured suitable earth working devices 6, in this instance shovels, but disks or other types may be used. As shown and described Fig. 1 of the drawings, being an elevation shows but one side of the cultivator, on the opposite side however, similar parts are carried, the following description therefore will apply to both sides of the cultivator. The gan beam 4 is of the usual well known type of two connected beams spaced apart and connected together. A brace 7 is secured to the lower end of the support 3 and to the forward part of the frame 1; a similar brace 8 is secured to the lower end of the support 3 and extends upwardly and rearwardly to the rear of the frame 1 where it is secured.

Rigidly secured on'the frame 1 is a rearwardly projecting segment 9 having notches 10. Pivotally supported on the rear of the frame 1 is a hand lever 11 provided with the usual type of latch to engage with the notches in the segment 10. Preferably integral with the lever 11 and extending forwardly therefrom is an arm 12 having pivotally connected to its forward end a rod 13 which projects downwardly to a bracket Specification of Letters Patent.

I Patented J an. 6, 1920,

Serial No. 93,403.

14 secured on the gang beam 4; the bracket 14 is provided with a perforation through which'the rod13 projects and is held in place by a pin or cotter 15 which is inserted in a suitable hole in the rod 13 below the bracket 14, the perforation in the bracket 14 being sufficiently large to permit the gang beam 4 to rise freely on the'rod 13.

Pivotally connected to the forward end of the arm 12 Ba rod 16 extending downwardly forward of the rod 13 and playing freely through a perforation in a bracket 17 rigidly secured on the gang beam 4; a coil spring 18, on the rod 16exerts its pressure agzpinst the bracket 17 and a pin 19 on the roc 16.

The coil' spring 18 holds the cultivating gang, to the depth set, by pressure on the bracket 17 on the gang beam 4, the latter however can rise against the pressure, when an obstruction is encountered by the cultivating devices, the cotter 15 holding the gang. beam 4 against downward movement except by operation of the lever 11 and the pressure of the coil spring 18; the coil spring 18 also assists in lifting the gang beam 4 when the lever 11 is actuated rearwardly to raise the gang beam 4 through the connection of the lever therewith by the rod 13 and the cotter 15 acting against the underside of the bracket 14. In the drawings is shown in dotted lines the position of the raising mechanism and the gang beam when the lat ter is raised.

The operation of raising the gang beam is assisted by the spring 18 in the following manner; the latch on the lever 11- having been released from the notch in which it was set, the lever 11' swung rearwardly and downwardly consequently the arm 12 moves upwardly, raising the gang beam 4 through .95 j the connection of the rod 13 therewith and with the arm 12. When the gang beam 4 is 1 down and the lever 11 locked in position as shown 1n full lines in Fig. 1, the spring 18 1S contracted and exerts its tension between the bracket 17 and the pin or cotter 19, holdof raising the latter, the spring 18 exerts its expansive force in the direction of the faster moving arm 12 thus assisting in raising the latter and the beam 4: to which it is connected.

What I claim is 1. In a cultivator, the combination of a frame, a gang beam pivotally supported on the frame, a lever pivoted on the frame and operable to raise and lower the gang beam and having an arm extending forwardly from the pivot, a rod pivoted to the free end of said arm and extending downwardly to connection with the gang beam, a rod pivoted to the free end of said arm and having a sliding connection with the. beam, and a coil spring on said rod exerting its pressure to hold the gang beam down and cooperat ing with the lever to lift the beam.

2. In a cultivator, the combination of a frame, a gang beam pivotally supported on the frame, a lever pivoted on the frame and having an arm extending therefrom, a rod pivoted to the free end of said arm and extending downwardly to connection with the gang beam whereby the latter is raised or lowered by operation of the lever, a second rod pivoted to the free end of said arm and having a sliding connection with the gang beam at a point intermediate the connection of the first mentioned rod with the beam and the pivotal connection of the beam with the frame, and a coil spring on said second rod, said spring acting to hold the beam down and cooperating with the lever to raise the beam.

In testimony whereof I affix my signature, in presence of two witnesses.
